Ballistic impact analysis of balsa core sandwich composites

This work investigates balsa core sandwich composites with thin carbon fiber skins subjected to single and multi-site sequential ballistic impacts. For the sandwich composite composed of core and facesheet thicknesses of 0.95 cm and 0.25 mm respectively. The ballistic limit was determined to be 96 m s−1, indicating that it was capable of withstanding impacts from small projectiles such as, secondary debris from blast, hurricane, tornado and...
